To all whom it may concern.-

Be it known that I, EDMUND DEAN, a subject of the King of Great Britain, residing at Woodvale, South Notwood, London, England, have invented new and Im'pr'oved Appamtus for Transporting Bedsteads, of which the following is a specification.

My invention relates to a trolley or carriage designed to be pushed beneath a bedstead and provided with. mechanism for lifting the said bedstead, so that its weight is carried by the trolley, to permit of the said i edstead being readily transported fromplace to place.

' The apparatus constructed according to my invention (:1 mprises a frame mounted on caster wheels, preferably r: bbcr tired, and'on ball bearings so as to allow of the .ame being pushed beneath a bedstead either from the md or the side. In practice guides may be applied to the framing to insure that the carriage shall assume its proper position relatively with the bed to be lifted.

Thelifting apparatus is preferably composed of two beams arranged at the head and foot of the carriage and eachl'carried by two racks andpinions or screws, the pinions engaging with the several racksfor the nuts engaging with the several screws, being arranged to be operated simultaneously through the medium of suitable gearing. i i

' In the accompanying drawingsz-Figure l is aside View of my improved trolley or carriage. Fig. 2 is an end view, and Fig. 3 is a plan. Fig. 4 is a plan vie. drawn to a larger scale than Figs. 1 to 3, illustrating a inr.-diiication of my invention, and Fig.- 5 is an elevation of theparts shown in Fig. 4. Figs. 6 and 7 are views at right angles to each other of a crank handle hereinafter described; I i

a is the frame of the carriage which is advantageously made ofwood, although it may be made of bars or tubes of metal and b, bare the caster wheels for supporting the same, the said caster wheels being of such size that the frame maybe carried suificiently low down to permit of its being pushed beneath the bedstead, notwithstanding that the bed bottom of the latter may sag considerably. Orone side of the frame a is made lower at the center than the other side, shown at a, Figs. 1, 3 and 5, to allow it to clear the sagging bottom.

0, c are the bars or beams arranged at the ends of the r carriage and designed to bear against the under-sides of the bedstead frame, adjacent to thc head and foot, for As shown in the drawing, these beams c, 1:, which may be provided upon the top with pads or cushions c, e for lessening vibration, are each arried by two bars (1, at having rack teeth and sliding in suitable guides d, d in thel'rai'no a. With the ra ck teeth of these bars engage pinions 1:, e mounted on shafts/",fwhich connect the pinions on the opposite sides of the carriage in pairs. These shafts f carry Worm wheels y, g with which worms h,h on a transverse shaft 1', mounted in suitable bearings in the frame, on-

a e in such a manner that when-the said'shaft i is rotated rotary motion will bosimultaneouslyimparted to all the pinionsc, a so that all four rack bars, livgether with the bars (2, c which they carry, will be lifted at'lhe same time; In the drawing the shaft i is represented as being adapted to be rotated by meansof acrank handle j through the medium of the pinion It and gear wheel I. the latter of which is fixed to the shaft 11.

It will be understood that the various wheels, worms and pinions must be so proportioned that a number 0t revolutions of the crank handle, is necessary to effect one revolution of the pinions a so that the bed can be lifted with little effort.

Instead of employing racks and pinions, as described, the beams c, a may be supported byscrews carrying nuts adapted to be simultaneously rotated or adapted themselves to be rotated in fixed nuts.

.The crank handle which I advantageously employ has the handle proper jointed to the lover or Erank so that when not required for use it may be turned to lie in the plane of the said crank and so occupy little space. As shown, the crank is formed in two parts.

telescoping one within the other, the outer tubular part having a bayonet slot j, Figs. 6 and 7, which engageswith a lug j oirthe' inner part. A spring j holds the parts in the locked position and is compressed when the lug is disengaged from the notch of the bayonet slot and the handle. turned to the dotted position, Fig. 6.

In order that the carriage, wheirbeing pushed beneath the bedsteaibshalltake up a proper position relatively with thela-tter, it is provided on its ends with guide bars m, m which lit between the legs of the bedstead, which legs, in Fig. 3, are indicated by dotted circles m, m the said guides m, m terminating in books 17, n which )revcnt the carria e from-bein". i i a is pushed too far undcr the bed. This arrangement of the guide bars with hooks enables the carriage to be used for beds of slightly different length as with a long bed the-legs engage with the inside of the books, as

indicated'by the dotted circles m m"..

In order. to provide for using the carriages in connection with beds the frames of which are of varying height, .I advantageously arrange in connection with the beams 0,0, loose chocks o, 0, which are normally 4 carried inside the frame by means of dowel pins and shelves at d which, when the carriage is to be used in connection with a bedstead having a high frame, can be placed upon the tops of the beams c, c, the dowel pins fitting into holes p, p in the said beam as ind icatod in Figs. 4 and 5', hooks (1, (1 upon the beams engaging with the (hooks to hold them in position, as indicated in Figs. 2 and 5. The said sepiarateblocks can be hinged to the beams and so arranged as to be flush with the top of the beams when not in use.

IIaving new particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I'- claim is 1. In ah apparatus ofthe kind described, the combination with a horizontal rectangular frame of substantially the size of a bed and mounted on supporting wheels, one side of said frame being lower than the opposite side thereof, of vertically adjustable horizontal beams mounted at the ends of said frame andsubstantially at right angles with said lower side of said frame, substantially as described.

2. In an apparatus of the kind described, the combinatlon with a horizontal rectangular frame of substantially the size of a bed but adapted to fit under the same and mounted on supporting wheels, said franbdbeing pro- 3. In an apparatus of the kind described, the combination with asubstantlally rectangular frame, .of vertically adjustable horizontal beams mounted on said frame and parallel to the ends thereof, guides secured to the ends of said frame, said guides being provided at corresponding ends with outwardly projecting hookhportions and wheels for supporting said frame, substantially ns described.

,4. In an apparatus of the kind described, the combination with a frame mounted on caster wheels, of, vertically adjustable horizontal beams mounted on said frame, checks adapted to be placed on said horizontal beams and having dowel pins adapted to fit in recesses in said beams and to said beams, substantially as described. v I
